L=(2W+1)
A=LW
A=36
{{{36=LW}}}
{{{36=(2W+1)W}}}
{{{36=2W^2+W}}}
{{{0=2W^2+W-36}}}
{{{0=2(W^2+0.5W-18)}}} -4 and 4.5 are the 2 numbers that multiply to get -18 add to get 0.5
{{{0=2(W-4)(W+4.5)}}}
{{{W=highlight(4)}}},{{{cross(-4.5)}}} cant be negative
{{{L=(2W+1)}}}
{{{L=(2(4)+1)}}}
{{{L=highlight(9)}}}
